HORSESHOEL SPECIFICATION forming part'of Letters Patent No. 302,185, dated July 15, 188%.

(No model.)

To all whom/zit may concern: 1

Be it known that 1, JAMES F. Arwoon, of Boston, in the county of Suffolk and State of Massachusetts, haveinvented new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates to that class of horseshoes in which the shoes are double-i. 6., consisting of a permanent and detachable shoethe object of such construction being to enable the detachable shoe to be readily and quickly removed and another put into its place.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a View in perspective of my improved horseshoe. Fig. 2 is a plan view of Fig. 3 is a plan View with the shoes in the-.act of being separated or put together. Fig. 4 is a vertical section on line a, Fig. 2, a portion being represented as broken out for the purpose of showing one of the springs, &c. g

A represents the upper or permanent shoe, provided with the shortened and beveled heels A and A. The beveled end of the heel A is preferably, but not necessarily, at about a right angle to the edges of the heel portion of the shoe. The heel A" is beveled on the line of a curve, as shown. The permanent shoe is also provided with a recess, whose long or rear edge, a, is beveled, as shown in Fig. 4, and whose ends or short edges a are perpendicular (at right angles to the surface of the shoe A) and preferably out upon a slight curve.

A recess is provided next the outer edge of I the shoe, between the toe-recess and the heel A, whose long edge I) is preferably perpendicular, whose edge I) is beveled, and is substantially at right angles with the edge I), and whose edge I) is beveled and is at an obtuse angle with the edge I). Opposite this recess is a recess whose long edge a is preferably perpendicular and whose short edges 0 c are beveled, as shown, and are nearly at right angles to the edge a.

d d are perforations, the object of which is below explained.

B is the detachable shoe or under one, pro vided with the raised heel-pieces B and B, of the exact shape to fit over the beveled heels A A", and toe-piece 6, having the perpendicular ends e and beveled side 6, so as to g and h h h are adapted to fit into the recesses b b b and c c 0, respectively, and the ordinary calks, I.

The shoes are put together (the permanent shoe A having been first nailed to the horsels foot) by laying the detachable shoe B in the position shown in Fig. 8, and then swinging it laterally into coincidence with the permanent shoe. This would be impossible if the heel-piece B were of the shape of the heelpiece B, or if the edges 9 and b were at right angles with the outer edge of the shoe at that point; hence I make the edges A and I) decidedly curved and the edges a and c slightly.

In order to prevent relative lateral (or horizontal) movement sidewise and to make them self locking, I provide grooves k, ending in perforations 7c in the detachable shoe B. Secured in these grooves, as shown in Figs. 3 and 4, are springs Z, supporting bolts a, lying in the perforations is. incident, the bolts a spring into the perforations d in the shoe A, and of course extend downward also into the perforations k in the shoe B, thus effectually locking the shoes together.

Pressure downward upon the bolt is sufficient to unlock the shoes, which may then be quickly taken apart. The headsn of the bolts a are made sufficiently large to cover the perforations 7c, and thus keep out dirt, 6:0.

It will be readily seen that to remove a dull detachable shoe constructed as above described and apply a sharp one is a very simple and quick operation.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the permanent shoe A, provided with the curved beveled heel A, and detachable shoe B, provided with the raised and beveled heel-piece B, curved to correspond with the curvature of the heel A, the said shoes being adapted to be rigidly secured together elsewhere, substantially as and for the purpose set forth.

2. The combination of the permanent shoe A and the detachable shoe B, the latter being provided with one or more dovetails upon its surface, said dovetails being curved at one end, and the former being provided with recesses hen the shoes are made 00- .7 5

corresponding to and fitting over such dovetails, si'lbstantially as and for the purpose described.

3. The combination of the permanent shoe A and the detachable shoe B, the latter being provided with one or more raised or upwardlyprojecting pieces curved at one edge, and the former being provided With one or more recesses corresponding to and fitting such pieces, substantially as and for the purpose specified.

4. The combination of the permanent shoe A, provided with the recess at the toe, beveled at c and curved and perpendicular at a, and the detachable shoe B, provided with the toepiece 0, beveled at e and curved and perpendicularat c, said shoes being provided with means for securing the heels together, sub stantially as and for the purpose set forth.

5. The combination of the permanent shoe A, provided with the toe-recess a a and the respectively straight and curved heels A and A, and the detachable shoe B, provided with the toe-piece e and heel-pieces B B, substan tially as and for the purpose described.

6. The combination of the permanent shoe A, provided with the toe-recess a a, the recesses I) b b and c c c, and the heels A A, and the detachable shoe B, provided with the toe-piece e, heel-pieces B B", and dovetails g it, all substantially as and for the purpose set forth.

7. The combination, with the permanent shoe A, provided with the perforations d, of the detachable shoe B, provided with the grooves k, perforations 7t, springs Z, and bolts a, all substantially and for the purpose specified.
